Between 1975 and 1980, 16,586 sonograms, including repeat scans, were obtained on pregnant women for various obstetric indications. The diagnosis of polyhydramnios was made 78 times by an experienced sonographer as a simple observer judgment of an excess amount of amniotic fluid. In pregnancies thus diagnosed, the fetus was then carefully scanned for anomalies, and repeat scans were done. Major clinical problems encountered are discussed.
